The Littlest Hobo follows the adventures of a highly intelligent German shepherd named London, who wanders the country, befriending people in trouble and helping to remedy their situation. He then declines their offer to adopt him as a pet, leaves them, and continues his hobo life. Among the names given to London by his human friends are Smoke, Einstein, Scout, Mr. Magic, Lucky, Shadow, Buddy, Slapshot, Roamer, Crusoe, Ulysses, Hercules, Sinbad, and Gulliver.
